District heating & district cooling

District heating water

A city-wide, low-temperature district heating system is key to any low-carbon city. The system is cost-effective and uses efficient, carbon neutral heat sources that would otherwise be wasted, such as that from CHP plants with heat accumulators, waste-to-energy plants, geothermal plants, biomass boilers, large-scale heat pumps and large-scale solar heating plants. Even for small settlements, district heating with thermal storage can be the key component of the most intelligent, cost-effective and carbon neutral heating for both existing and new buildings.

Ramboll is a leading engineering consultancy in district heating with more than 40 years of experience in Denmark and in more than 25 other countries. Our services include all stages of planning, design, operation, maintenance and management, and include technical, institutional, legal as well as economic aspects of the work. Our international market for these services is growing, not least due to growing concern with climate change.

District heating steam and super-heated water

A special system for district heating, based on super-heated water or steam, is used mainly for industrial processes, but also in some cities and hospitals. Ramboll has 40 years of experience with these systems, including the design of pipe systems with a proven lifetime of more than 50 years. We also have experience transforming these systems into more efficient, low-temperature systems.

District cooling

Decentralised electric chillers in district cooling systems can often be replaced by less expensive systems that use cold seawater, groundwater or carbon-free thermal energy. Our experience in district cooling includes chilled water storage, district cooling absorption chillers and centralised cooling plants.

Heating installations in buildings

The efficiency of a city-wide heating system depends on its integration with low-temperature heating systems in buildings. We provide our customers with expertise in the design and operation of all facilities in the system, including building installations.
